hundred feet. It was named L. dyspelor Cope. The centra were de- 

 pressed in the dorsal region, and had the smooth margin bordering the 

 ball and rugose surface within this band. An emargination for the neural 

 canal. Caudals pentagonal anteriorly, becoming soon higher than wide. 

 From near Fort McRae, New Mexico. 



Several other species of the order had recently been found by Prof. 

 Mudge in Kansas. Two of these were Lioclons, and were named L. 

 ictericus and L. mudgei, respectively. The former was allied to L. validus 

 Cope, having depressed dorsal vertebrae ; but the quadrate bone had a 

 less prominent and more medially placed external angle and ridge. The 

 L. «md(/eniad depressed vertebrae ; but the external angle of the quad- 

 rate more posterior, and not continued so far down. The third was a 

 Clidastes, much the largest of the genus, nearly equalling the Liodon 

 validus in size, and differing from the described species in the lack 

 obliquity of the articular extremities, and other points. He named it 

 Clidastes cineriarum Cope.
